Using Red Light to 改善 代谢 & the Harmful Effects of LEDs | Dr. Glen Jeffery

这 section of the episode develops the topic 通过 the following source points: 安德鲁·休伯曼： Let's talk 关于 indoor lighting, 因为 I am 非常 concerned 关于 the amount of short-wavelength light 那 人们 are exposed to nowadays, 尤其是 kids. Glen Jeffery: Mm-hmm. 这 is an issue on the same 水平 as asbestos. 这 is a public health issue, 和 it's big. 和 I think it's 一 of the reasons why I'm 确实 happy to come here 和 talk, 因为 it's time to talk. When 我们 use LEDs, the light found in LEDs, when 我们 use them, certainly, when 我们 use them on the retina looking at mice, 我们 可以 watch the mitochondria gently go downhill. They're far 更少 responsive. Their membrane potentials are coming down. The mitochondria are not breathing 非常 well. 可以 watch 那 in real-time. 安德鲁·休伯曼： Welcome to the Huberman Lab 播客, where 我们 discuss science 和 science-based tools 对于 everyday life. I'm Andrew Huberman, 和 I'm a professor of 神经生物学 和 ophthalmology at Stanford School of Medicine. My guest today is Dr. Glen Jeffery, a professor of neuroscience at University College London. In today's episode, 我们 discuss how 你 可以 use light, in particular red, near-infrared, 和 infrared light, to 改善 你的 health, 和 no, not just by getting sunlight, 尽管 我们 do talk 关于 sunlight. Dr. Jeffery's lab has discovered 那 certain wavelengths 或 colors of light 可以 be used to 改善 你的 皮肤, 你的 eyesight, even 你的 血液 sugar regulation 和 代谢. Dr. Jeffery explains how light is absorbed by the 水 in 你的 mitochondria, the 能量-producing organelles within 你的 cells, to allow them to function better by producing 更多 ATP. He also explains how long-wavelength light, things like red light, 可以 be protective against mitochondrial damage caused by excessive exposure to things like LED bulbs 和 screens, which of course 我们 are all exposed to pretty much all 天 long nowadays, 和 simple, inexpensive, 和 even zero-cost ways 那 你 可以 get long-wavelength light exposure, 和 again, not just by getting 更多 sunlight. He explains 那 long-wavelength light 可以 actually pass 进入 和 通过 你的 entire 身体, 和 那 it scatters when inside 你. Now, 那 可能 sound scary, 但 it's actually a great thing 对于 你的 health, 因为 那's how long-wavelength light 可以 改善 the health of all 你的 organs, by entering 你的 身体 和 supporting 你的 mitochondria. Believe it 或 not, certain wavelengths of light 可以 actually pass 通过 你的 skull 进入 你的 大脑 和 help promote 大脑 health. 期间 today's episode, 我们 also discuss new findings 那 correlate the amount of sunlight 你're exposed to 与 longevity. 那些 are 非常 surprising findings, 但 they're 重要. Also, why everyone needs some UV light exposure. 和 我们 discuss whether it's 重要 to close 你的 eyes when using red light devices 或 in red light saunas, 和 how best to apply red light 和 things like infrared light in order to derive maximum health benefits. Today, 你're going to learn 从 一 of the greats in neuroscience as to how to use light to 改善 the health 和 longevity of any 和 every 组织 in 你的 身体, 和 the mechanisms 对于 how 那 works. 之前 我们 begin, I'd like to emphasize 那 这 podcast is separate 从 my teaching 和 研究 roles at Stanford.
